As algae are the main route of selenium (Se) transport from water to other consumers in food webs, the effect of selenite on the total Se content, growth, and antioxidant status of the unicellular green alga Monoraphidium cf. contortum was determined. The basal Se content (<3mg/kg DW) was lower compared to other green microalgae, but the species showed a high accumulation potential (284.1mg/kg DW). Despite early Se accumulation and growth inhibition, a significant loss of chlorophylls and carotenoids was observed only after 72hours. The response of antioxidative enzymes corresponded to a lower intensity of lipid peroxidation, despite increased ROS content at lower selenite concentrations. Primarily, selenite increased the activities of ascorbate peroxidase (APX), glutathione reductase, glutathione peroxidase (GPX), and glutathione S-transferase (GST), and inhibited catalase (CAT) in almost all treatments. Higher GST and GPX activities, as well as selenite-induced non-enzymatic glutathione (GSH) oxidation indicated increased GSH depletion.
由于藻类是食物网中硒从水中转运到其他消费者的主要途径,因此研究了亚硒酸盐对单细胞绿藻(Monoraphidium cf. contortum)总硒含量、生长和抗氧化状态的影响。其硒的基础含量(3mg/kg DW)低于其他绿微藻,但积累潜力较大(284.1mg/kg DW)。尽管早期硒积累和生长抑制,但仅在72小时后才观察到叶绿素和类胡萝卜素的显著损失。尽管亚硒酸盐浓度较低时ROS含量增加,但抗氧化酶的反应与较低强度的脂质过氧化反应相对应。在几乎所有处理中,亚硒酸盐增加了抗坏血酸过氧化物酶(APX)、谷胱甘肽还原酶、谷胱甘肽过氧化物酶(GPX)和谷胱甘肽s -转移酶(GST)的活性,抑制了过氧化氢酶(CAT)的活性。较高的GST和GPX活性,以及亚硒酸盐诱导的非酶促谷胱甘肽(GSH)氧化表明GSH消耗增加。

Glyphosate, the most widely used herbicide, is primarily applied to control unwanted weeds. While its impacts on pollinators such as honey bees have been extensively studied in agricultural settings, exposure from non-crop flora in urban environments remains largely overlooked. This gap is critical, as urban greenspaces function both as refuges for pollinators and as potential, underrecognized pathways of herbicide contamination. We investigated glyphosate residues in pollen collected by honey bee foragers from non-crop plants across an urbanization gradient in Suzhou, China, over an entire growing season. Using DNA metabarcoding and LC-MS/MS analysis, we identified pollen sources and quantified glyphosate residues in 71 composite samples from 11 sites along an urbanization gradient, with built-up coverage ranging from approximately 10% to 70%. Glyphosate was detected in 83.1% of samples, with concentrations up to 880 μg/kg. Residue levels showed a non-linear relationship with urbanization, with glyphosate concentrations decreasing initally and then increasing as the proportion of built-up areas increased. No significant correlation was detected between glyphosate occurrence (detection frequency or concentration) and pollen diversity. These results reveal that non-crop flora in urban greenspaces represent a season-long pathway of glyphosate exposure for honey bees, highlighting the need to integrate pollinator health considerations into urban vegetation and herbicide management strategies.
草甘膦是使用最广泛的除草剂,主要用于控制有害杂草。虽然在农业环境中对蜜蜂等传粉媒介的影响进行了广泛研究,但在城市环境中对非作物植物群的暴露仍在很大程度上被忽视。这一差距至关重要,因为城市绿地既是传粉媒介的避难所,也是潜在的、未被充分认识的除草剂污染途径。研究人员调查了中国苏州城市化梯度下非作物植物采集的蜜蜂花粉中草甘膦残留的整个生长季节。利用DNA元条形码和LC-MS/MS分析,我们在城市化梯度的11个站点的71个复合样品中鉴定了花粉来源并量化了草甘膦残留,这些站点的建筑覆盖率约为10%至70%。在83.1%的样品中检测到草甘膦,浓度高达880 μg/kg。草甘膦残留量与城市化呈非线性关系,随着建成区比例的增加,草甘膦残留量先降低后升高。草甘膦的出现(检测频率或浓度)与花粉多样性无显著相关。这些结果表明,城市绿地中的非作物植物群代表了蜜蜂暴露于草甘膦的一个季节路径,突出了将传粉媒介健康考虑纳入城市植被和除草剂管理策略的必要性。

Rapid urbanisation in Low- and Middle-Income Countries (LMICs) has driven the expansion of urban and peri-urban farming to enhance food security. However, these systems are highly vulnerable to contaminated irrigation waters, urban runoff, open defecation and inadequate sanitation, and anthropogenic pollution, such as plastic and microplastic waste. Here, we investigated the role of plastic debris as a reservoir and vector for multidrug-resistant (MDR) enteric bacterial pathogens in a real-world agronomic setting. Focusing on two peri-urban agricultural sites in Dar es Salaam, Tanzania, we analysed 140 environmental samples (soil, water, vegetation, and surface and buried plastic debris) for the presence of four key enteric pathogens: E. coli, Salmonella spp., V. cholerae, and K. pneumoniae. The concentration of total culturable pathogens was higher on plastic debris compared to soil, water and vegetation, with presumptive E. coli loads of ∼1x103 CFU per individual piece of plastic debris. Importantly, plastic debris harboured a greater proportion of MDR strains; specifically, 69% of E. coli isolates were resistant to two or more antimicrobials, with plastics at one site accounting for over half of all MDR E. coli. While MDR E. coli were absent from soil, plastic debris supported strains of E. coli and K. pneumoniae that were resistant to critically important antimicrobials (e.g., ciprofloxacin and cefixime)..This study provides robust evidence that in a real-world setting, plastic waste can act as an ecological reservoir which concentrates and facilitates the survival of MDR pathogens. Therefore, the widespread presence of contaminated plastic in agricultural systems could pose significant occupational health risks for farmers, in addition to a potential environment-to-food risk for consumers.
低收入和中等收入国家(LMICs)的快速城市化推动了城市和城郊农业的扩张,以加强粮食安全。然而,这些系统极易受到灌溉水污染、城市径流、露天排便和卫生设施不足以及人为污染(如塑料和微塑料废物)的影响。在这里,我们研究了在现实世界的农艺环境中塑料碎片作为多药耐药(MDR)肠道细菌病原体的储存库和载体的作用。我们以坦桑尼亚达累斯萨拉姆的两个城郊农业地点为重点,分析了140个环境样本(土壤、水、植被以及地表和掩埋的塑料碎片),以确定存在四种主要肠道病原体:大肠杆菌、沙门氏菌、霍乱弧菌和肺炎克雷伯菌。与土壤、水和植被相比,塑料碎片上的总可培养病原体浓度更高,估计每片塑料碎片上的大肠杆菌负荷为1 × 103 CFU。重要的是,塑料碎片中含有更大比例的耐多药菌株;具体而言,69%的大肠杆菌分离株对两种或更多种抗菌素具有耐药性,其中一个地点的塑料占所有耐多药大肠杆菌的一半以上。虽然土壤中没有耐多药大肠杆菌,但塑料碎片支持大肠杆菌和肺炎克雷伯菌菌株,这些菌株对至关重要的抗菌剂(例如环丙沙星和头孢克肟)具有耐药性。这项研究提供了强有力的证据,证明在现实世界中,塑料废物可以作为一个生态水库,集中并促进耐多药病原体的生存。因此,受污染塑料在农业系统中的广泛存在,除了可能给消费者带来从环境到食品的风险外,还可能给农民带来重大的职业健康风险。

The persistence of per- and polyfluoroalkyl substances in the environment is becoming a major health concern, yet studying their fate and behaviour in complex media is limited due to the lack of suitable analytical methods. Here we proposed that a fluorescent polyfluoroalkyl probe could enable rapid tracing and negate drawbacks associated with current techniques. We synthesised a fluorescent probe containing a maleimide motif grafted to perfluorooctanoic acid. Using a conductivity assay, the critical micelle concentration was determined, and cryogenic transmission electron microscopy was further utilised to verify the presence of multilamellar vesicles. Titration of the fluorescent probe with a base enabled the determination of the acid dissociation constant, an important property of perfluorooctanoic acid. Results show that this fluorescent probe exhibits similar properties to perfluorooctanoic acid, and thus could reasonably act as an environmental proxy, with the benefit of strong, concentration-dependent and environmentally responsive fluorescence. This fluorescence offers a facile entry point for real-time tracing in various media. Further exploration of this tracer through plant, concrete, or soil studies could enable a better understanding of per- and polyfluoroalkyl substance behaviour in range of natural and artificial media.
全氟烷基和多氟烷基物质在环境中的持久性正在成为一个主要的健康问题,但由于缺乏适当的分析方法,对它们在复杂介质中的命运和行为的研究受到限制。在这里,我们提出了一种荧光多氟烷基探针可以实现快速追踪,并消除与当前技术相关的缺点。我们合成了一种含有接枝到全氟辛酸的马来酰亚胺基序的荧光探针。通过电导率测定,确定了临界胶束浓度,并进一步利用低温透射电子显微镜验证了多层囊泡的存在。用碱滴定荧光探针可以测定酸解离常数,这是全氟辛酸的一个重要性质。结果表明,该荧光探针具有与全氟辛酸相似的特性,因此可以合理地作为环境代理,具有强、浓度依赖和环境响应的荧光。这种荧光提供了一个方便的切入点,实时跟踪在各种媒体。通过植物、混凝土或土壤研究进一步探索这种示踪剂,可以更好地了解全氟烷基和多氟烷基物质在各种自然和人工介质中的行为。

Can membrane aerated biofilm reactor (MABR) realize more efficient simultaneous partial nitrification and denitrification than conventional biofilm under low COD/N? 在低COD/N条件下,膜曝气生物膜反应器(MABR)是否能比传统生物膜更有效地同时进行部分硝化和反硝化?

Simultaneous nitrification and denitrification (SND) is an efficient nitrogen-removal process, yet its application in low COD/N wastewater is limited in conventional co-diffusion biofilms due to carbon source waste and microbial competition. Membrane aerated biofilm reactors (MABR) could theoretically realize more efficient SND by employing counter-diffusion biofilms to separate oxygen and carbon sources. However, the SND efficiencies were not satisfactory in previous publications, possibly because excessive aeration and uncontrolled nitrite-oxidizing bacteria (NOB) growth increased the demand for carbon sources. Herein, three MABRs using oxygen-affinity PP-PDMS membranes were operated with an extremely low aeration pressure (0.6 kPa) to initiate SND in high-strength nitrogen wastewater (200 mg/L NH4+-N) with low COD/N (R1: 2; R2: 3; R3: 4). A stable simultaneous partial nitrification and denitrification (SPND) was established in R2 and R3 (TN removal of 73.8% and 79.8%, respectively), which was higher than the reported co-diffusion biofilms. Increased COD/N did not significantly enhance nitrogen removal once SPND was established. Microbiological analysis indicated that ammonia-oxidizing bacteria (AOB) and archaea (AOA) both contributed to nitrification, and NOB were incompletely suppressed. Fluorescence in situ hybridization (FISH) and mass transfer calculation revealed that carbon sources inhibited NOB and enhanced oxygen transfer by increasing the oxygen concentration gradient. However, nitrate accumulation and COD waste still occurred and led to a gap between MABR and single denitrification because of the unavoidably high oxygen at the membrane-biofilm interface. Overall, counter-diffusion biofilms outperformed co-diffusion biofilms in TN removal, but entire SPND was still hard to be attained.
同时硝化反硝化(SND)是一种高效的脱氮工艺,但由于碳源废弃物和微生物的竞争,传统共扩散生物膜限制了其在低COD/N废水中的应用。膜曝气生物膜反应器(MABR)利用反扩散生物膜分离氧碳源,理论上可以实现更高效的SND。然而,SND效率在以前的出版物中并不令人满意,可能是因为过度曝气和不受控制的亚硝酸盐氧化细菌(NOB)生长增加了对碳源的需求。在低COD/N (R1: 2, R2: 3, R3: 4)的高强度含氮废水(200 mg/L NH4+-N)中,采用氧亲和PP-PDMS膜的3种mabr在极低曝气压力(0.6 kPa)下启动SND。在R2和R3中建立了稳定的同时部分硝化和反硝化(SPND), TN去除率分别为73.8%和79.8%,高于已有报道的共扩散生物膜。建立SPND后,COD/N的增加并没有显著提高氮的去除率。微生物学分析表明,氨氧化菌(AOB)和古细菌(AOA)均对硝化作用有贡献,NOB未被完全抑制。荧光原位杂交(FISH)和传质计算表明,碳源通过增加氧浓度梯度抑制NOB,增强氧传递。然而,由于膜-生物膜界面不可避免的高氧,仍会产生硝酸盐积累和COD浪费,导致MABR与单次反硝化之间出现间隙。总体而言,反扩散生物膜去除TN的效果优于共扩散生物膜,但仍难以达到完整的SPND。

Ammonia-Assisted Combustion of Alcohol-Enriched Chicken Fat Biodiesel: Experimental Investigation of a Multi-Fuel Strategy in Diesel Engines 氨辅助燃烧富醇鸡脂生物柴油:柴油机多燃料策略的实验研究

This study aims to develop a sustainable multi-fuel strategy for diesel engines by examining the combustion, performance, and emission characteristics of industrial chicken-fat biodiesel (B100) enriched with 2-ethyl-1-hexanol (2-EH) and supplemented with ammonia (NH3) fumigation. The objective is to overcome limitations of neat biodiesel, such as high viscosity, low volatility, and incomplete combustion, while enhancing overall engine efficiency. Five test fuels (D100, B100, 2-EH5%B100+NH3 5lpm, 2-EH10%B100+NH3 5lpm, 2-EH15%B100+NH3 5lpm) were evaluated in a single-cylinder diesel engine operating at 1500rpm under five brake-load conditions (0-100%). Combustion parameters, performance metrics and emissions were measured. NH3 fumigation was supplied at 5 lpm using a controlled intake-manifold system. Combustion analysis demonstrated that B100 exhibited weaker premixed combustion than D100, as evidenced by lower in-cylinder pressure and heat-release rate (HRR) peaks. Under full load conditions, the blend 2-EH15%B100+NH3 5lpm achieved the greatest combustion, with in-cylinder pressure around 48.05% higher than B100 and 3.22% higher than D100. The maximum HRR was nearly 70% greater than B100 and about 6.7% higher than D100, indicating intensified premixed heat release near top dead centre. Brake thermal efficiency (BTE) increased by 14.8% compared with B100 and 3.7% over diesel, while brake specific energy consumption (BSEC) decreased by 28.7% relative to B100. Significant emissions reductions in carbon monoxide (CO) by 37.5%, hydrocarbon (HC) by 11.1%, and smoke opacity by 35.3% were observed compared with B100. However, oxides of nitrogen (NOx) emissions increased by 33.1%, attributed to enhanced premixed combustion and higher in-cylinder temperatures. The synergistic combination of waste-derived biodiesel, higher alcohol, and NH3 fumigation enhances combustion phasing, improves thermal efficiency, and substantially lowers major pollutants except NOx. Although the strategy introduces a NOx penalty, it demonstrates strong potential for cleaner, more efficient diesel-engine operation and may be further optimized through future NOx mitigation technologies.
本研究旨在通过研究富含2-乙基-1-己醇(2-EH)和补充氨(NH3)熏蒸的工业鸡脂生物柴油(B100)的燃烧、性能和排放特性,为柴油发动机制定可持续的多燃料策略。目标是克服纯生物柴油的高粘度、低挥发性和不完全燃烧等局限性,同时提高发动机的整体效率。5种试验燃料(D100、B100、2-EH5%B100+NH3 5lpm、2-EH10%B100+NH3 5lpm、2-EH15%B100+NH3 5lpm)在一台转速为1500rpm的单缸柴油机上进行了5种制动负荷工况(0-100%)评估。测量了燃烧参数、性能指标和排放。NH3熏蒸在5lpm使用控制进气歧管系统。燃烧分析表明,B100比D100表现出较弱的预混燃烧,缸内压力和热释放率(HRR)峰值较低。满负荷工况下,2-EH15%B100+NH3 5lpm的混合气燃烧效果最好,缸内压力比B100高48.05%左右,比D100高3.22%左右。最大HRR比B100高近70%,比D100高约6.7%,表明在上死点附近预混放热加剧。制动热效率(BTE)比B100提高了14.8%,比柴油提高了3.7%,而制动比能耗(BSEC)比B100降低了28.7%。与B100相比,一氧化碳(CO)排放量显著减少37.5%,碳氢化合物(HC)排放量显著减少11.1%,烟雾不透明度显著减少35.3%。然而,由于预混燃烧增强和缸内温度升高,氮氧化物(NOx)排放量增加了33.1%。垃圾生物柴油、高酒精和NH3熏蒸的协同组合增强了燃烧的分相,提高了热效率,大大降低了除NOx以外的主要污染物。虽然该策略引入了氮氧化物惩罚,但它显示了更清洁、更高效的柴油发动机运行的强大潜力,并可能通过未来的氮氧化物减排技术进一步优化。

The use of fungicides is an integral part of field crops cultivation for the management of several diseases; however, the potential for fungicides to exert sublethal impacts on the biology of non-target insect pests is an understudied area with serious management consequences. Aedes albopictus is one of the most common human disease vectors and non-target aquatic insect species inhabited in and/or around several field crops. Here, we studied the effects of tebuconazole on several biological traits of Ae. albopictus. Biological traits and population parameters of a strain of Ae. albopictus were studied after exposing it to the LC5 (62.09 mg L-1), LC10 (86.31 mg L-1), or LC20 (128.62 mg L-1) level of tebuconazole for five consecutive generations and were compared with an unexposed control group. The results revealed that LC5 and LC10 levels had hormetic (stimulatory) effects, while the LC20 level posed non-hormetic (inhibitory) effects on the performance of most of the life history parameters. The developmental period of egg, larval, and pupal stages of the LC5 and LC10 groups were faster than in the LC20 and control groups. The performance of biological parameters of the LC5 and LC10 groups such as preadult and adult survival rates, preoviposition period, oviposition days, and fecundity was better than that of the LC20 and control groups. The mean generation time was significantly shortened in the LC5 and LC10 groups. Moreover, higher values of the net reproductive rate (R0) and finite rate of increase (λ) were recorded in the LC5 and LC10 groups than in the LC20 and control groups. In conclusion, the findings of the present study revealed that exposure of Ae. albopictus to sublethal levels of tebuconazole may favor its rapid development, enhanced fecundity, survival and population expansion under field conditions, thereby increasing the probability of Ae. albopictus-borne infections.
杀菌剂的使用是田间作物栽培中管理几种病害的一个组成部分;然而,杀菌剂对非目标害虫生物学产生亚致死影响的潜力是一个研究不足的领域,管理后果严重。白纹伊蚊是最常见的人类疾病媒介之一,也是栖息在几种大田作物内和/或周围的非目标水生昆虫。本文研究了替布康唑对伊蚊几种生物学性状的影响。蚊。一株伊蚊的生物学特性和种群参数。对白纹伊蚊连续5代暴露于LC5 (62.09 mg L-1)、LC10 (86.31 mg L-1)、LC20 (128.62 mg L-1)浓度的戊康唑下进行研究,并与未暴露对照组进行比较。结果表明,LC5和LC10水平对大多数生活史参数的表现具有激效(刺激)作用,而LC20水平对大多数生活史参数的表现具有非激效(抑制)作用。LC5组和LC10组的卵期、幼虫期和蛹期发育均快于LC20组和对照组。LC5和LC10组的成虫前存活率、成虫存活率、产卵期、产卵天数、繁殖力等生物学指标均优于LC20组和对照组。LC5组和LC10组的平均世代时间显著缩短。LC5和LC10组的净繁殖率(R0)和有限增重率(λ)均高于LC20和对照组。总之,本研究的结果表明,暴露于伊蚊。在野外条件下,苯康唑可使白纹伊蚊快速发育,增强其繁殖力、存活率和种群扩张,从而增加白纹伊蚊感染的可能性。albopictus-borne感染。

Green manure (GM) has strategic value in the context of sustainable agriculture and climate change. However, few studies have analyzed the effects of GM on regulating the carbon footprint (CF) through the dynamic coupling of soil organic carbon (SOC) and greenhouse gases (GHG) using the meta-analysis method, and there have also been insufficient assessments of the potential reductions of global emissions based on changes in CF. Thus, by combining global meta-analysis and machine learning predictions, we demonstrated that while GM increases CH4 and N2O emissions by 22.05% and 2.94% respectively, it significantly enhances SOC stocks by 9.59%. This increase in SOC effectively offsets the carbon cost of GHG emissions, reducing the total carbon emissions by 33.37% and CF by 36.23%. Machine learning predictions indicate that GM can reduce the global CF by 42.18%, with notable crop-specific and spatial heterogeneity, where the response is most pronounced in wheat systems (63.30%), weaker in rice systems (19.94%), and negative feedback may occur in regions with high soil fertility. These findings provide a theoretical basis for developing precise carbon management strategies using GM as a global paradigm.
绿肥(GM)在可持续农业和气候变化的背景下具有战略价值。然而,很少有研究利用meta分析方法分析转基因通过土壤有机碳(SOC)和温室气体(GHG)的动态耦合对碳足迹(CF)的调节作用,并且基于CF变化对全球排放减少潜力的评估也不足。因此,将全球meta分析与机器学习预测相结合,结果表明,GM使CH4和N2O排放量分别增加22.05%和2.94%,SOC储量显著增加9.59%。SOC的增加有效地抵消了温室气体排放的碳成本,碳排放总量减少了33.37%,CF减少了36.23%。机器学习预测表明,转基因可使全球CF降低42.18%,具有显著的作物特异性和空间异质性,其中小麦系统的响应最明显(63.30%),水稻系统的响应较弱(19.94%),并且在土壤肥力高的地区可能出现负反馈。这些发现为利用转基因作为全球范例制定精确的碳管理策略提供了理论基础。

This study presents a comprehensive review of the emerging role of Generative Artificial Intelligence (GenAI) in environmental assessment and sustainability analysis. Positioned within a new paradigm of environmental management, GenAI redefines traditional static models through dynamic, generative, and participatory approaches that integrate data synthesis, scenario modeling, and governance insight. Using a Systematic Literature Review (SLR) guided by the CIMO (Context-Intervention-Mechanism-Outcome) framework, this paper identifies and analyzes 182 scholarly and technical publications published between 2015 and 2025. The review synthesizes developments across key GenAI architectures-Generative Adversarial Networks (GANs), Variational Autoencoders (VAEs), Transformer-based Large Language Models (LLMs), and Diffusion Models-and evaluates their applications in synthetic data generation, scenario simulation, remote sensing, predictive analytics, and public engagement. The findings reveal that GenAI holds significant potential to address data scarcity, enhance model scalability, and promote participatory and interdisciplinary decision-making, while also presenting challenges related to interpretability, data bias, validation, environmental footprint, and ethical governance. To guide responsible implementation, the study proposes a three-tier framework emphasizing technical fidelity, transparency, and governance alignment. The implications underscore that effective integration of GenAI into environmental management requires hybrid modeling, participatory data governance, and sustainable AI infrastructures to ensure transparency, accountability, and equity. Collectively, this work advances an evidence-based understanding of how GenAI can underpin a data-driven, inclusive, and ethically responsible paradigm in environmental assessment.

本研究全面回顾了生成式人工智能(GenAI)在环境评估和可持续性分析中的新兴作用。GenAI定位于环境管理的新范式,通过集成数据合成、场景建模和治理洞察力的动态、生成和参与式方法重新定义了传统的静态模型。本文采用CIMO(情境-干预-机制-结果)框架指导下的系统文献综述(SLR),对2015年至2025年间发表的182篇学术和技术出版物进行了识别和分析。该综述综合了GenAI关键架构的发展——生成对抗网络(gan)、变分自动编码器(VAEs)、基于变压器的大型语言模型(LLMs)和扩散模型,并评估了它们在合成数据生成、场景模拟、遥感、预测分析和公众参与方面的应用。研究结果表明,GenAI在解决数据稀缺、增强模型可扩展性、促进参与性和跨学科决策方面具有巨大潜力,同时也提出了与可解释性、数据偏差、验证、环境足迹和道德治理相关的挑战。为了指导负责任的实施,该研究提出了一个强调技术保真度、透明度和治理一致性的三层框架。这些影响强调,将GenAI有效整合到环境管理中需要混合建模、参与式数据治理和可持续的人工智能基础设施,以确保透明度、问责制和公平性。总的来说,这项工作促进了对GenAI如何支持数据驱动、包容和道德负责的环境评估范式的循证理解。
